RF Connector footprint

berms03

Im trying to create a RF connector footprint, but dont know how to go about it.  The fooprint is a ring that is a GND pin and then inside the ring there is a signal pin.  The footprint is similar to www.tycoelectronics.com/.../TE.Connect click on drawling.  I tried to use an annular padstack and a round pad stack, but that didn't work to well cuz orcad uses the center of padstacks to make connections.  Any suggestions would be much appreciated 

  • Let's say you want to have that ground ring encompass 6 vias.  Make one a pin and the rest vias.  Then the schematic symbol simply needs a single ground pin but the symbol will always tie the "ring" and the remaining 5 vias to ground.  The signal pin is just a pin.

    You might have to "touch" the ground ring in the board if it does not assign the ring to the net GND but it should.

    To build the ring, just add a filled shape in a circle. 

  •  Thanks for the quick response.  I thought of doing something similiar, but wasn't sold 100 percent on doing it this way

  • I actually have changed my RF connector symbols to have a ground pin in the schematic for every attach point on the board.  Done it both ways and over time have realized that neither way is more attractive.  Pick a method and stick to.

    Hope it's all working.
